Abstract
A method and an arrangement for determining the position of a tape-like medium are proposed. The method provides for counting pulses which are supplied to the arrangement for determining the position to be counted, blocked or cancelled depending on the respective transport state. To this end, it is established whether the transport direction has been constant for a defined amount of time or over a defined distance. The transport direction determines whether the counter is incremented or decremented. In addition, counting pulses which rapidly follow one another are blocked in order to avoid undesirable double triggering. In order to avoid losing blocked counting pulses in an undesirable manner, the latter are stored and are applied to the counter, or discarded, depending on the transport state before and after blocking.
